To all whom t may concern; y f y i Bemit knovvn that We, Jol-IN EMA-Nunn loi-raison and @nannies l-l. Usnonn, citizens ofthe United States, residing` atfvlorcester, in the county ofVorcester and ctateof Masi sachusetts, have `invented a new and useful `BottleestingMachine, ofavhich the fol-` lowing` is a specification. y i

ThisV invention relates to a gmachine'for testing1 capped or sealed. bottles or other. re ceptacles to show any imperfection` in sealing, and at the same time agitatingg the bote tleso as to mix the contents which usually enn'iprise a thin` and a thick liquid.

. The principal objects of the invention are to; provide for effectively ksecuring` these` tivo advantage-si While ,the hotties l.are passing` from a crowningor czupping` machine,` or

Fig. 2v is aside elevation ofthe same With i the tank shown in section;

Fig. 3 is a transverse sectional view line 3--3 of Fig. 1; p y y Figi'. e is a transverse sectional view on the line ie-lof Fim 1; andllig. '5 isl a similar on the b view on the line 5-5. i Y p We have shown the invention as comprising; a testing tank 12 receiving'ybottles B from a crowning machine A' Which passes them out on a conveyor 13 in a horizontal position and at an elevation above the Water i e form. They remain in inclined positionfor in the tank 12 invvhich the conveyor. 13 runs.`

n will be noted that the bottles in ailing` from the crowner` platform to the'conveyor `.land in inclined position on a ruhber buffer 9` and are jarred sufficiently toassist in mixingzjtheir contents. They are taken alonghby the conveyor' in a. direction at right angles to their line` of motion on the crowner plata short distance and then this conveyor passes down on theguides 15, which support it. Thisbrings the bottles intohorizontal `position and dovvnbelow the level of the Water; The sides of thetank enclose guides 1e to engage the ends of the bottles and keep them in proper position on the conveyor.

This conveyor is made up of links 16vpivot- `ally connected `together and eachhaving a plate 127 extending from it at right angles. These plates are spaced apart far enough to admit bottles between them. The flat parts of` the link 16 run under a pair of stationary supports 18 on Which the bottles roll as they travel along with the conveyor. mixing purposes. While the bottles are immersed in the Water in this Way theyerr counter a longitudinalguide 19 at the side This is for farthest from the crowner, that is the side y over which proj ectthe `neolrs of theybottles. This guide is secured along1 the inside of the tank by bracletsilocated on the sides thereof and supports the necks above the butts so as to incl ne the bottles under Water. lf` there isl any defect in the crowning sufcient to admitmuch air or gas, `this is indicated by `the..'alnaearance of bubbles in the Wateryand the attendant removes the defective bottles.

water causes the air caught therein to rise to the `neck of the bottle and escape under Water if the sealing is not perfect, fully showing `the defect and permitting of the rlhexinclinaton of the bottles While under removal.. The fact that the bottles are rolling' alongmakes this still more perfect.

The bottles are brought back to horizontal position With some degree of jarring and with a further mixing` of their contents, when they reach the end of the guide 19, the top of which is horizontal. This guide entends horizontally from the incline doivn` into the tank at thereceiving end nearly to the incline at the discharge end. The conveyor passes up` the'latter incline and `brings the bottles up out of the Water, their testing having been completed at this time.

TVV hen the bottles arrive on end table 2O `they are carried along a short distance `horizontally and then encounter an inclined guide. 21 over the conveyor shown as carried by one of the guides 15 which raises them upslightly at-the crowned end. Just thenthey pass over a curvedplate 22 which is supported by a part of the stationary side Walls of thetank and therefore they slide doivnover this surface into an upright position which further jars them and mixes their contents. y

.n rlhe bottles can be carried off from this point in any desired Way, but We have shown the top `of an a discharging conveyor which preferably is a part ot the labeling machine C, and therefore delivers the bottles to that machine. This conveyor comprises the usual conveying belt, the construction of which is not described in detail as it forms no part of this invention, but it also involves a short endless carrier 2S traveling over the conveyor 25. This carrier 28 is made of links having ,plates 27 forming recesses 29 between them,

through a shaft 32 and gearing- 33. All

these elements are shoivn asv supported by an extension 34 on the end oi the tank 12.

The operation of the machine has practically been described already, but it may be stated in generalthat the bottles come 'trom `the crowner in vertical position and they are dumped oii' the endetl this support on the conveyor on ivhich they land in inclined position, thus jarring the bottles and mixing their contents` Theythen pass down under ivater and travel along in it 'for a distance with a rolling motion, meantime being inclined so that their necks are at the top to facilitate discharge of any air caught in them in the process oi.l crowning. They are tested bythe operator observingany bubbles that arise in the ltank. The defectively sealed bottlesl are removed by hand. The remainder ot the bottles, thoroughly tested, are agitated iturther'as they roll along `vvith the conveyor and are given a hnal agitation 'ivhen they are discharged on their endsl in the labeling machine conveyor.

' ...although We have illustrated and described a single embodiment o1" the invention and shown it as connected ivith a erowning` and labeling machine ive are aware of the fact that modifications can be made in the construction and ,relative arrangement of the parts, and that the invention can be used in connection with other machines Without departingfrom the scope of the invention. as expressed in the 'claims Therefore' We do not Wish to be limited to these Jeatures and combinations, but what We do claim is '1. ln a testing machine, the combination o'l a tank ior holding Water, and means t'or receiving'bottles, iminersing them in Water, rolling them along therein, and inelining .them While inthe water to a position with their necks np to 'facilitate the discharge ot any air in the bottles under water.
